The surface areas (SBET) of the resultant activated carbons were
in the range of 970–1432m2/g, which were comparable to the
values for bamboo-based activated carbons reported in literature.
Wu et al. (1999) reported a surface area range of 553–1038m2/g
by steam activation, while the group of Hameed (Hameed and
El-Khaiary, 2008; Hameed et al., 2007) reported higher values
(>1700m2/g) by activation with K2CO3/CO2 or NaOH/CO2. The activated
carbons obtained in this study had higher surface areas than
most of the commercial carbons (Wu et al., 1999).
